Gzipin

Gzipin is a hypothetical lossless data compression format described as an extension of the gzip algorithm. It is intended to improve compression efficiency for modern data while remaining compatible with existing gzip tooling where possible.

Gzipin uses a block-based streaming design that supports random access to compressed data and parallel encoding and decoding. The header carries metadata such as original size, profile selection, and optional integrity information. The compression core combines a dictionary-based LZ77-like coder with entropy coding and supports multiple compression profiles to tune speed and ratio.

To maintain interoperability, gzipin seeks a backward-compatible block interface so decoders can skip unrecognized blocks and still recover data. It emphasizes streaming friendliness, enabling on-the-fly compression of large files and progressive decompression of initial blocks. Optional per-block and per-file checksums are envisioned to improve data integrity.

Status and adoption are experimental. There is no formal standard published, and mainstream development centers on gzip and related formats. Some proposals exist in academic or educational contexts and in experimental libraries, but gzipin remains a topic of theoretical discussion rather than a widely used format.
